Description

  The present invention includes a stove body, a top plate that covers the top surface of the stove body, a stove burner that protrudes on the top plate through a burner opening provided in the top plate, and a burner opening that surrounds the burner opening on the top plate. It relates to a gas stove with five virtues.

  Conventionally, this kind of gas stove has a burner ring that is placed on the top plate in an extrapolated state on the stove burner, and the virtues are positioned by externally fitting a five-virtual annular virtuosity frame to this burner ring. It has been known. A gas stove is also known in which an annular ridge corresponding to the above-described burner ring, which is positioned on the top plate at the peripheral edge of the burner opening and fitted with a five-virtual annular virtuosity frame, is drawn (for example, a patent). Reference 1). According to this, burnering becomes unnecessary, and the number of parts can be reduced to reduce the cost.

  However, it has been found that the following problems occur when an annular ridge is drawn on the top plate. In other words, the annular ridge is easily heated by the radiant heat from the flame of the burner, the top plate is thermally expanded by heat input from the annular ridge, and the top plate is deformed so that the annular ridge is displaced upward. It becomes easy. And once the annular ridge is displaced upward, the amount of heat input to the annular ridge increases to approach the flame, and the upward displacement of the annular ridge due to the thermal expansion of the top plate becomes considerably large. End up. For this reason, when the top plate cools and contracts due to the stop of combustion of the stove burner and tries to return to the initial state, a large reversing sound is generated and the user is surprised.

  In view of the above, the present invention provides a gas stove that suppresses the upward displacement of the annular ridge during burner combustion and prevents the occurrence of a large reversal sound at the top plate during cooling. Is the issue.

  In order to solve the above-mentioned problems, the present invention provides a stove body, a top plate that covers the top surface of the stove body, a burner that projects on the top plate through a burner opening provided in the top plate, and a burner on the top plate. A gas stove comprising a virtues placed so as to surround the opening for use, and is located on the top plate at the peripheral edge of the opening for the burner, and the annular bulging portion on which the virtually annular virtuosity frame is fitted is throttled In the molded object, a reinforcing member extending from the annular ridge to one side of the top plate is fixed to the lower surface of the top plate, and the stove body is prevented from floating upward at the end of the reinforcing plate on one side of the top plate. An engaging portion to be engaged is formed.

  According to the present invention, since the engaging portion at the end portion of the reinforcing member is engaged with the stove body so as not to float upward, the upward displacement of the annular raised portion during combustion of the stove burner is suppressed by the reinforcing member. . As a result, it is possible to prevent a large inversion sound from being generated on the top plate during cooling.

  By the way, at the rear part of the top plate, an exhaust port for the grill incorporated in the stove body is opened, and an exhaust guard that covers this exhaust port is placed on the upper surface of the rear part of the top plate, and at the part located under the exhaust guard. The top plate may be screwed to the ceiling of the grill. In this case, the top plate may warp forward during cooling, and the front side portion of the top plate may float from the stove body. Therefore, when the top plate is screwed to the ceiling portion of the grill at the portion of the top plate located under the exhaust guard, the one side of the top plate on which the reinforcing member extends is preferably the front side of the top plate. According to this, the reinforcing member is engaged with the stove body at the engaging portion located on the front side of the top plate, and the front side portion of the top plate is lifted from the stove body due to the warping of the top plate during cooling. It can be surely prevented.

The perspective view of the gas stove of embodiment of this invention. The perspective view of the decomposition | disassembly state of the gas stove of embodiment. The expanded sectional view of the important section of the gas stove of an embodiment.

  Referring to FIG. 1, reference numeral 1 denotes a gas stove according to an embodiment of the present invention. The gas stove 1 includes a stove body 2, a top plate 3 that covers the top surface of the stove body 2, and a pair of left and right stoves that protrude on the top plate 3 through the burner openings 31, 31 provided at two left and right sides of the top plate 3. Burners 4 and 4, a pair of left and right virtues 5 and 5 placed on the top plate 3 so as to surround the burner openings 31 and 31, and a grill 6 incorporated in the stove main body 2 are provided. On the front surface of the stove main body 2, a fire extinguishing button 21 and a heating power adjusting lever 22 for each of the stove burners 4 and a grill burner (not shown) are arranged.

  Referring also to FIG. 2, an exhaust port 32 is formed at the rear portion of the top plate 3 so as to face an exhaust outlet 62 opened at the rear end of the ceiling portion 61 of the grill 6. 7 is placed on the upper surface of the rear part of the top plate 3. A fixing hole 33 is formed in the portion of the top plate 3 located under the exhaust guard 7, and a screw hole 63 is formed in a portion matching the fixing hole 33 of the ceiling portion 61 of the grill 6. The top plate 3 is screwed to the ceiling portion 61 of the grill 6 with screws that are screwed into the screw holes 63 so that the user cannot easily remove the top plate 3. In addition, a screwing location is covered with the exhaust guard 7 and does not appear on the appearance, and the appearance is not impaired.

  Each of the five virtues 5 is formed by attaching a plurality of five virtue claws 52 radially to an annular five virtue frame 51. The top plate 3 has an annular ridge 34 formed at the periphery of each burner opening 31, and the five virtues 5 of the five virtues 5 are externally fitted to the annular ridge 34. Each Gotoku 5 is positioned.

  By the way, the annular ridge 34 is easily heated by the radiant heat from the flame of the burner 4 so that the top plate 3 is thermally expanded by the heat input from the annular ridge 34 and the annular ridge 34 is displaced upward. The top plate 3 is easily deformed. Then, once the annular ridge 34 is displaced upward, the amount of heat input to the annular ridge 34 is increased to approach the flame, and the upward displacement of the annular ridge 34 due to the thermal expansion of the top plate 3 is increased. It becomes quite large. For this reason, when the top plate 3 is cooled and contracted by the combustion stop of the stove burner 4 and attempts to return to the initial state, a large reversal sound is generated and the user is surprised. Further, when the top plate 3 is screwed to the ceiling 61 of the grill 6 at a portion located below the exhaust guard 7 as in the present embodiment, the top plate 3 warps forward when cooling, and the top plate 3 There is a possibility that the front side portion of the will rise from the stove body 2.

  Therefore, in the present embodiment, a reinforcing member 35 extending from the annular ridges 34 to the front side of the top plate 3 is fixed to the lower surface of the top plate 3 by welding or the like, and the front side of the top plate 3 of the reinforcing member 35 is fixed. As shown in FIGS. 2 and 3, an engaging portion 35a that engages with the stove main body 2 is formed at the end portion, that is, the front end portion so as not to float upward. More specifically, the reinforcing member 35 is formed of a U-shaped member having bent portions 35b downward on the left and right sides, and protrudes forward from the bent portions 35b to the front end portion of the reinforcing member 35. A claw piece-like engaging portion 35a is formed. Further, a slit 24 corresponding to the engaging portion 35 a of each reinforcing member 35 is formed in the frame 23 at the upper front end of the stove body 2. Then, after inserting the engaging portion 35a into the slit 24, the top plate 3 is slightly shifted forward, and the engaging portion 35a is engaged with the lower surface of the frame 23 portion ahead of the slit 24 so as not to float upwardly. In this state, the top plate 3 is screwed to the ceiling portion 61 of the grill 6 through the fixing hole 33.

  According to this, the engagement of the engaging portion 35a with the stove main body 2 prevents the entire reinforcing member 35 from being displaced upward, so that the annular ridge 34 is reinforced to displace upward when the stove burner 4 burns. It can be suppressed by the member 35. As a result, it is possible to prevent a large inversion sound from being generated on the top plate 3 during cooling. Further, the reinforcing member 35 is engaged with the stove main body 2 by the engaging portion 35a located on the front side of the top plate 3, and the front side portion of the top plate 3 is caused by the warp of the top plate 3 during cooling. It is possible to reliably prevent floating from the main body 2.

  As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to this. For example, the above embodiment is provided with a grill, and the rear portion of the top plate 3 is screwed to the ceiling portion 61 of the grill 6, but this is also applied to a gas stove with or without a grill that does not screw the rear portion of the top plate 3. The invention can be applied, and in this case, the reinforcing member 35 may extend from the annular ridge 34 to the rear side of the top plate 3 or one of the left and right sides.
